Why Every Modern Companion Left Doctor Who
7. Matt Lucas - Nardole
Much like Catherine Tate, Matt Lucas was a popular comedy star who nobody expected to make more than one appearance in a Christmas special. Instead, he went on to become the Doctor's beloved valet/punching bag in a full season and two more Christmas specials. Like his co-star Pearl Mackie, he was signed on for one season and some specials in this strange transitionary period between the Moffat and Chibnall eras.
Peter Capaldi, Matt Lucas and Pearl Mackie made a great team together, and it's disappointing that it was all too brief, due to the changes being made behind the scenes.
